My biology teacher recently showed us a video of evolution.
It suddenly showed one day when DNA existed, and replicated itself, gained a membrane and lived on.
How could something so complex and alive form from chemicals.
I don't understand it.
I would like some help, so thanks in advance.

The science of evolution is something that may one day be open to the public for people to copy but for know the problem is that the people cant figure out how life started because the religions all say that thier god created man and science says taht we evolved from monkeys and it has always been a subject of great deliberation.

I think most agree that RNA came first.

Also, something "so complex and alive" is not spontaneous. And everything is formed from chemicals.

The reasoning for this is that RNA actually provides the method for replication of RNA. The polymerases and such are made of RNA. So once you have RNA, it's possible to synthesize new RNA. Not so for DNA.

??? are we talking about origin of species or the origin of life. yes jbdan said about evolution. but in my mind the meaning of evolution is releated to the chemical evolution. so i think jbdan not said about the origin of species.
